+X API rate limits vary by endpoint, auth method, and account tier, and they change over time. Always:
+- Check the current X developer docs before hardcoding assumptions
+- Read `x-rate-limit-remaining` and `x-rate-limit-reset` headers at runtime

 ## Integration with Content Engine
 
-Use `content-engine` skill to generate platform-native content, then post via X API:
-1. Generate content with content-engine (X platform format)
-2. Validate length (280 chars for single tweet)
-3. Post via X API using patterns above
-4. Track engagement via public_metrics
+Use `brand-voice` plus `content-engine` to generate platform-native content, then post via X API:
+1. Pull recent original posts when voice matching matters
+2. Build or reuse a `VOICE PROFILE`
+3. Generate content with `content-engine` in X-native format
+4. Validate length and thread structure
+5. Return the draft for approval unless the user explicitly asked to post now
+6. Post via X API only after approval
+7. Track engagement via public_metrics
